Workbooks.Open sets 'Saved' flag on other workbook

[brettacook]

I have this interesting behavior that I'd like to see if I can avoid. I'm using Excel 2016.

                Set YearWorkbook = Workbooks.Open("Generator.xlsm")
                Dim DescriptionsWorkbook As Workbook
                Set DescriptionsWorkbook = YearWorkbook
                Dim DescriptionWorksheet As Worksheet
                Set DescriptionWorksheet = DescriptionsWorkbook.Worksheets("Descriptions")
                Dim EventSheet As Worksheet
                Set EventSheet = YearWorkbook.Worksheets("Events")
                Dim WorkbookName As String
                WorkbookName = "Results.xlsx"
                On Error Resume Next
                Dim ResultWorkbook As Workbook
                Set ResultWorkbook = Workbooks.Open(WorkbookName)
                On Error GoTo 0
....

When the the code executes the 'Set ResultWorkbook = Workbooks.Open(WorkbookName)' line, the value of 'YearWorkbook.Saved' goes to False (it should be True because there have been no modifications to that workbook).

Has anyone seen this behavior before? And if so, is there an explanation for this behavior and/or a workaround? (Or, is there some obvious coding error that I've made?)

Thanks!

Interesting further information: this behavior occurs only if the 'Results.xlsx' file already exists. If the 'Results.xlsx' file does not exist, the value of 'YearWorkbook.Saved' stays as True.
